2.1 INTENDED USE
The sprayer in this series is built for agricultural use. The materials used are
resistant to normal chemical products used in agricultural spraying (or herbicides)
at the time of construction.
Any other use is not allowed and the manufacturer is not responsible for any
damage caused by aggressive, dense or sticky chemicals.
THE USE OF THE MACHINE BY PERSONS UNDER 18 YEARS OF AGE IS
STRICTLY FORBIDDEN
The use of liquid fertilizers in suspension is not allowed, while the use of the
same in a solution is possible if requested when the machine is ordered from
Unigreen and in any case changing some of the parts described in the handbooks
of the regulator, such as the manometer (stainless steel), the nozzles (large
diameter ceramic) and eliminating the fine mesh filters to prevent blockages.
2.2 PROHIBITED USE
Using the machine with the following products is strictly forbidden:
= Paints of any kind and type
= Solvents or thinners for paints of any kind and type
= Combustibles or lubricants of any kind and type
= LPG or gas of any kind and type
= Flammable liquids of any kind and type
= Liquid foodstuffs, whether for animals or humans
= Liquids containing granules or consistent solids
= Mixtures of various incompatible chemical products
= Liquid fertilizer or manure in suspension with lumps and/or that is particularly
dense
= Liquids with a temperature of over 40°C
= Any products that aren’t suitable for the specific use of the machine.
2.3 USING CHEMICAL PRODUCTS
All pesticides or herbicides can be dangerous to humans and the environment if
used erroneously or inadvertently.
Therefore we recommend that only suitably trained persons should use these
products (license) and in any case only after having carefully read the instructions
on the container.
2.3.1 REGULATIONS FOR THE USE OF CHEMICAL PRODUCTS
Some recommendations for avoiding damage and accidents:
= Keep the machine in a suitable, protected place with no access for children or
strangers
= Handle the products with care, wearing rubber acid-proof gloves, goggles- face
masks or filtering helmets, overalls made of water-repellent fabrics or TIVEK and
boots made of rubber or similar materials.
= If chemical products or mixtures of product come into contact with the eyes or
are swallowed consult a doctor immediately, taking the label of the product with
you.
= Wash all clothes that come into contact with the chemical, whether diluted or
undiluted, thoroughly before using them again.
= Don’t smoke, drink or eat when preparing or spraying the mix or near or in the
fields treated.
= DON’T ENTER THE TANK: the residues of a chemical product can cause
poisoning and suffocation.
= When spraying, respect safe distances from residential areas, water courses,
roads, sports centres and public parks or paths.
= Thoroughly wash the containers of plant protection products using the relevant
accessories, rinsing several times with clean water. The liquids used for washing
can be used for treatment.
= Collect the washed containers and send them to the relevant collection
centres. Never dispose of them in the environment and don’t use them again for
any other purpose. It is good practice to knock a hole in the bottom of the tins so
they can’t be used again.
= When you have finished spraying, wash the sprayer thoroughly, diluting the
residues with a quantity of water at least 10 times that of the residues, spraying
the resulting mix over the treated field.

2.4 RECOMMENDATIONS a) Refer to the present handbook for the use and maintenance of the frame, tank,
auto-levelling systems, elevators, mechanical and hydraulic herbicide booms,
spray booms and hose reels.
Refer to the enclosed handbooks for the use and maintenance of the pump and
pressure regulator and any accessories or motors.
b) Please contact the agent in your zone, the nearest authorised workshop or
UNIGREEN S.p.A. directly for any repairs the user feels they aren’t capable of
performing alone. (see point 10.4)
c) Due to the complexity of the equipment and the variety of technologies used
(mechanical, hydraulic, oil-pressure and electrotechnical) operators must not
dismantle or modify the equipment. All of the relevant operations must be performed
by specialised personnel, authorised by UNIGREEN S.p.A.
2.4.1 TAKING PRECAUTIONS AGAINST FIRE HAZARDS
Don’t use naked flames or heat sources near the machines.
The sprayers are made with many materials that derive from petroleum: tanks,
tubes, pipes and hoses, wheels and plastic parts; furthermore the presence of
oils of various nature and residues of chemical products make them potentially
flammable.
2.5 WEATHER CONDITIONS
We recommend spraying in the early hours of the morning or late in the afternoon,
avoiding the hottest time of day.
Never do any spraying if it’s raining or rain is forecast.
Don’t spray in strong wind or in any case, in winds above 3/5 m/second.
If you have to spray in windy conditions, use relatively low pressures to obtain
quite large drops that are less sensitive to drifting (being heavier the wind has
less effect). There are also special anti-drift nozzles available from UNIGREEN
S.p.A.; for information, please contact our offices.
2.6 MACHINES DESIGNED TO BE USED ONLY WITH CLEAN WATER
There are versions of the machines designed only to be used with a hose reel for
washing with cold clean water.
These machines cannot be used with chemical products as they don’t have some
of the devices or accessories that are needed to use these products safely.
These machines are identified by the word “washing” on the CE plate.
2.7 DRIVING ON THE ROAD
The CAMPO series atomisers are not specifically designed for road use.
Nevertheless, many models are also available in the version homologated for
road traffic with the tank empty.
You should check with your local reseller on the correct couplings to use and use
tractors that meet the regulations in force.
3 CHARACTERISTICS AND SPECIFICATIONS
This handbook is valid for tractor-mounted sprayers to be used with:
a) horizontal booms per herbaceous cultivations (herbicides, insecticides,
fungicides, foliage nutrient, etc.)
d) treatments with hand lances with or without a hose reel
e) hand lances for washing with or without a hose reel
The UNIGREEN S.p.A. sprayers are identified by the CE plate (FIG. 1 ) bearing

machine used to wash
your hands
4 USER’S INSTRUCTIONS
4.1 DESCRIPTION OF THE MACHINE
The sprayers are made of a structural steel frame and a polyester tank reinforced
with fibreglass or high-density polyethylene.
The frame is painted with special fired epoxy paints or, depending on the
versions, hot galvanised. The tank is easy to empty and this makes it possible to
use the machine even on hillsides.
The pumps are generally diaphragm pumps but in some cases fitted with pistons.
The accessories that can be used to complete the sprayer include: lifting devices,
self-levelling devices, mechanical or hydraulic herbicide booms, jets and nozzles
and this makes the UNIGREEN sprayer a highly qualified and efficient piece of
equipment.
4.1.1 HAND WASHING TANKS
The sprayers are supplied with an auxiliary hand-washing tank with clean water
and a hand tap.
This tank must always be supplied with water and the inside must be clean so
you can wash any parts of the body that come into contact with the chemical
product used.
Never drink the liquid inside.
4.2 PRELIMINARY CHECKS
When you receive the machine, check that it is complete and no parts are
missing.
If there are any damaged parts, inform your local reseller or UNIGREEN
directly in good time.
When the machine is delivered, make sure you ask:
a) that the machine is delivered with all of its parts fitted and that the fitting
meets the requisites in table N° 12a page 29. (This procedure is necessary
because for reasons of space during transportation the machine is often
delivered partially dismantled).
b) that it is tested in your presence in particular checking:
= that the suction filter and the inside of the tank are clean and free of work
residues.
= that the connections are made correctly following the basic layout (FIG. N°
11).
= that the hose clips and all the unions and connections are tightened
properly.
= that any herbicide boom is mounted in the centre.
= that all of the protective covers are fitted solidly to the machine, in particular
the protective cover of the power-takeoff of the pump.
4.3 TRANSPORTING AND MOVING THE MACHINE
Every time you have to lift the machine, before starting the operation, always
make sure the lifting gear and the relevant tools and equipment (cables,
hooks, etc..) are suitable for lifting the load and check the stability of the
same.
The dry weight of the machine at the maximum level of fitting and with all the
accessories allowed is stamped on the nameplate; use slings and lifting gear
with a adequate load-bearing capacity.
Don’t stand the sprayer on soft ground or steep slopes.
Never lift or move the sprayers by hand if there is liquid in the tank. The
machine will weigh more and the movement of the liquid can change the centre
of gravity causing uncontrolled movements.
We recommend using slings as shown in the figure, the lifting points to use on
the machine are indicated with the relevant symbol.
Don’t lift the machine with the forks of a forklift truck because the machine can
tip over due to the overhanging weight of the booms.
Don’t pass or stand under the machine when it is being lifted.
This symbol
identifies the
coupling points of
the machine
4.3.1 TOWED SPRAYERS
The towed sprayers have a folding parking wheel so the machine can be
moved around by hand on flat, compact ground, with the tank empty. In
general the use of the relevant chocks is necessary (supplied with the
machine and positioned on the two sides of the same, as shown in the figure
to the side) to guarantee the stability of the machine.
To lift the machine, follow the instructions above.

A
Tractor coupling for Towed machines:
- (A) standard version, with elevator coupling
- (B) homologated version, coupled to tow hook
4.4 TRACTOR COUPLING
B
The tractor must have a 1”3/8 ASAE DIN 9611/A power-takeoff that runs at
550 rpm. It must have a 3-point elevator suitable for safely supporting the
weight of the sprayer. Check this by consulting the table of allowed fittings N°
12a page 29.
WARNING: make sure there are no persons or things near the sprayer before
starting the machine and while you are using it.
a) Check the diameter of the elevator coupling pins. If necessary position the
double diameter pins correctly; there are also appropriate adapter bushes
available.
b) If the machine is coupled to the tractor by a tow hook, adjust the height of
the hook to keep the tank of the atomiser horizontal.
If the machine is coupled to the tractor by the elevator, retract the parking
wheel to stop it getting damaged during work (important: the parking wheel can
only support the EMPTY weight of the atomiser). Keep the towed machine
level with the control of the elevator.
c) On the versions with the telescopic support of the pressure regulator, adjust
it so it is easy to reach from the driver’s seat.
d) Check that the weight on the elevator can be born by the tractor (roughly
500 kg in the 2000 litre version).
e) Check that the tow bar steering joint is lubricated with grease.
f) If you need to adjust the gauge of the wheels of the towed machine, in any
case make sure the blocking screws of the axle shafts and the rim bolts and
any spokes of the wheel disc are tight.
To adjust the gauge, lift the towed machine as shown in point 4.3.1.
g) Check the pressure of the wheels (shown on the tyres).
Tractor coupling for homologated Towed
machines in work position (not suitable for
road use).
4.4.3 HYDRAULIC CONNECTION TO THE DISTRIBUTORS
The machines that need a hydraulic connection to drive the herbicide booms
are equipped with 1/2", “Push-Pull”, quick-fit male couplings. You can connect
the pipes by simply pushing them in, making sure you:
- proceed only with the engine turned off;
- lower any tools connected to the elevator of the tractor;
- carefully clean the two parts that will be coupled
Warning: the hydraulic cylinders used are the “Double Effect” type.
Consult the use and maintenance manual of the tractor.
4.5 CARDAN SHAFT
In some models this is supplied on request.
The cardan shaft must bear the CE mark.
It must always have its own instructions that must be followed scrupulously
and it should come with a cover bearing the mark, integrated in every part.
You should have previously checked the length to avoid:
= if it is too long, DANGEROUS THRUST ON THE PUMP SHAFT
= if too short, the POSSIBILITY OF DANGEROUS BREAKAGES
THE MINIMUM OVERLAP OF THE TWO TELESCOPIC TUBES MUST
NEVER BE LESS THAN 1/3 OF THE LENGTH OF THE TUBES.
The power that can be transmitted by the cardan shaft must be at least equal
to that required to run the sprayer. Consider that the power necessary to run a
sprayer without the fan is practically the same as that of the pump, the power
rating can be found in the pump instructions handbook. Generally 20 bar
pumps need 20 hp; 50 bar pumps need 30 hp. These power ratings can be
found in tables N° 12a page 29.
